I don't know if that actually helps, but I did some searching.
According to what I found, Miika is the Finnish version of "Michael", which name means something like "Who is like God?". So I guess it's "someone resembling God." So I just put the kanji of 'God', and 'resemble' together. This is either '神酷似' or just '神似'. I'm no kanji expert, but I used this method to find kanji for my name. [Gergő > Gregory > Watcher > Mamoru (well, it would be Yotogi, but I couldn't find kanji for that because I suck) > 守]
I guess this is not what you're looking for but I thought I'd share this. This link however might help you:
